i iiimg; lo the limwmgs, Figure 1 is a roller 6 and relatively small idle rqllor 7 4 and table 11. The table 11 is preferably detachably held in working position by angular lugs 1314 secured to the side brackets 1.

The presser late 5 is held in working position with free cm for limited vertical movements by means of vertically disposed guide rods or studs 15 secured to the upper edges of the side frames 1 I ()n the threaded upper ends of the guide rods 15 are nuts 16, and on said rods are coiled springs 17 that react against said nuts 16 and against said presser plate to force the latter downward with a tension that is variable by adjustments of the said nuts. The forwardly projecting edge 5 of the presser late 5 is curved upward so that the doug loaf carried by the receiving portion of the belt 4 would be carried under the said presser plate, causing the latter to rise.

The dough loaf, which usually comes from the mixer and is .cut to' proper size by a socalled divider, would be delivered into a hopper 18 which, shown, is secured to the side frames 1 in position to deliver onto the apron 4 just in front of the Lip-turned edgefi of the presser plate 5.

Overlying the roller 6 is a cooperating loaf flattening roller 19, the shaft 20 of which, as

shown, is journalecl in boxes 21 that are adjustably mounted in the side frames 1 and are adapted to be held in different vertical adjustments by screws 22. Rigidly secured to v the side frames 1 and extending transversely across the machine, in front of the roller 19, is a supporting bar 23. Two laterally spaced pairs 0 ulleys 24 are journaled to the supporting ar 23 and are located below the same, one pair on each side of the transverse center of the machine, and just in front of the short upper roller 19. The loaf centering belts 25 run over the cooperating rollers 24 and over horizontally alined cooperating rollers 26 which, as shown, are journaled to the under side of angular bearings 27 rigidly secured to the side frames 1. The forwardly extended portions of these centering belts 26 converge toward the roller 19. The shaft of one of each pair of rollers 24 is provided with a miter gear 28 that meshes with one of a pair of miter gears 29 secured to a transverse shaft 30 mounted in suitable bearings 31 on the bar 23. This shaft 30, at one end, is provided with a spur pinion and at its other end with a pulley A belt 34 runs over the pulley 33 and over a pulley 35 carried by a short shaft 36 journaled in a suitable bearing 37 on one of the side frames 1. The inner end of this shaft 36 carries obliquely sethlades 38 that work close to the'upper portion of the apron'4 at one side of the transverse center of the machine, and serves as a loaf shifting device, as will hereinafter more clearly appear.

The roller shaft 20, at one end, is provided with a spur gear 39 that meshes with the pinto adjusting screws 59.

esasro ion 32 of the shaft 30, and a spur gear 8 of the roller shaft 8, and at its other end it is provided with a pulley 40 over which a power driven belt 41 runs to impart motion to said shaft 20, and from thence to all the running parts of the machine.

The side frames 1 are provided with rearwardlyprojecting bearing arms 1 in the vicinity of the roller shaft 20, and in these arms a shaft 42 is journaled. The shaft 42 carries a roller 43, and on the end portions of said shaft is pivoted a short frame made up of laterally spaced. arms 44. In the lower ends of the arms 44 is journaled an idle roller 45. A belt 46 runs over the rollers 43 and and is driven in the direction of the arrows marked adjacent thereto on Figs. 4, 6 and 7. One or more light coiled springs 47 yieldingly draw the lower end portions of the arms 44 forward so that the belt 46 tends to maintain frictional engagement with the apron 4. The arms 44 are provided with forwardly projecting lugs 48 in which a ceiling roller 49 is journaled. This roller 49 works close to the intermediate forward portion of the coiling belt 46 and is driven in the direction of the arrows marked adjacent thereto on Figs. 6 and 7. This roller 49 is preferably, but not necessarily, corrugated. At one end, the shaft 42 is provided with a sprocket 50 over which and a sprocket 51 on one end of the shaft of the roller 49 runs a sprocket chain 52. The so-called secondary rolling device is of very much the sameconstruetionas the said primary rolling device. Its endless apron or feed belt 53 runs over a large roller or drum 54 and over a small roller 55. The shaft56 of the drum 54 is journaled in the side frames 1 and is provided with a sprocket 57. The shaft of the small roller is journaled in bearing boxes 58-that are adjustably mounted in the side frames 1 and are subject The upper horizontally extended portion of the apron 53 runs over a table 60 that is detachably su )ported by angular bearings e1e2 secured to the side frames 1. At suitable intervals, the table 60 is provided with loosely journaled bearing rollers 63- that serve to reduce the friction between the apron 53 and the table 50.

The presser plate 64 that cooperates with the upper portion of the apron 53 and overlies the same, is mounted for vertical movement on upright rods 65 rigidly secured at their lower ends to the side brackets 1, and provided at their threaded upper ends with nuts 66 between which and said plate 64 coiled springs 67 are compressed. The forwardly projecting edge of the presser plate 64 is curved upward, as shown, at 64.

At one end, the heretofore noted roller shaft 4'2 is provided with a s rocket 68 that alines with a sprocket 69 on t ieshaft 8 of the roller (3. A sprocket chain 70 runs over the two sprockets (1."; and 69. On the shaft 8,

eidjacent to the sprocket 60, is a like sprocket 71 over which and the sprocket 57 on the roller shaft 56 runs it sprocketclmin 71 3.

Fig. 5* illustrates n. modified construction which is used when oval loaves, such as the usual rye loci, are to be made. in this modified. construction, concave rollers 73 are snhstituted for the table rollers if! and 63, and upwardly convened Presser plates 74 are substituted for the presser plates 5 and 64. in Figs. 1, 6, and 7 of the drawings, the dough leaf is ll'KllCiltl-cll by the character and in said Fig. 1 said leaf is indicated by dotted lines.

From the receiving hopper 18 the dough loaf drops onto the receiving portion oi the traveling apron 4 and is thereby carried under the primary prcsser plate 5, which date yields so as to permit the load to pass thereunder. The presser plate carries the upper portion of the loci while the lower portion of the loci is carried i'orwz'nil by the apron 4, thereby rolling the lost over and over and elongating, the some. .ilie reiirniost springs 17 of this )rinmrv rolling device are "first reused to yield so that the rear edge of the said plate 5 is first turned upward, nndnslthe loin is "ttSStKl forward, the forward sn'nws h 37 yield so that the lorward edge of sand plate is then turned upward. The said presser plate, thcrelorc, has :1 sort of rocking notion as the loci passes under the some.

The loaf rolled, and elongated in a dirc-etion tinnsversely of the machine, carried iorward from the prinnn'y prcsser plate 5 until the right bend thereof engaged by one of the oblique bind is 38 of the so-enllcd loaf shifting device, and the loci is then turned 'into a position extending longitudinally of the machine. The load" thus tnrncd is, by the alining belts 25 and the nnron l, carried endwise between the r%()(.i1iil(l flattening rollers 6 end 1i), and by these rollers is 'llnttoned out itpproxinnllcly nsshown in Fig. (3. The end of this llntlencd load is carried egninst the upwardly moving portion ol' the coiling belt 46, and by the letter is moved upward into engagement with the. coilingv roller 4%). By the combined nction oi the coiling belt and coiling roller moving in the directions oi the arrows nnirlied adjacent thereto in Figs. (3 and 7, and by the motion im arted thereto by the so-cnllcd llaittcnin c rol ers, the flattened loaf is rolled into it coil, as shown. in Fig. 7. The loel" is thus coiled or rolled up in :1 dire-1 ion at right angles to or trzmsversely of the direction in which the lonf was rolled hy the prinnirv rolling: dc-

vicc, towit, by. thcnpron 4- cm cooperatingpresser plate 5. Asthc size oil the coiled 102d increases, the coiling belt 46 moves on twerd, as ind' .zated in Fl", 7, and when the coil has heen completed and has been given drubbing finish. or skin 'by the action on the exterior thereof of the belts 4. 46 and roller 49, it is dropped into the receiving ortion of the traveling apron 53 of the so-ca led secondary rolling device. By this belt 53 the coiled lost is carried under the presser plate 64 and is pressed together and rolled in the same direction in which it was coiled, and in. a direction transverse. to the direction in which it was rolled by the primary rolling device. Under the rolling action reduced thereon by the secondary rolling ievice, the loaf is again elongated and is given approximately the form desired for baking.

in actual practice a machine constructed substantially as shown in the drawings has been found highly efficient for the purposes had in view.
